Abstract
An elevator car or counterweight, comprising a frame, the frame including an upright structure in which a safety brake is mounted so as to allow for lateral movement of the safety brake relative to the upright structure; at least a first vertically or obliquely extending cantilever spring; wherein a first end of the first cantilever spring is mounted to the upright structure; and wherein the first cantilever spring is arranged such that a point remote from the first end provides a biasing force to the safety brake when the safety brake moves away from a default position. As the safety brake is mounted to allow for lateral movement relative to the frame, the safety brake essentially floats relative to the car or counterweight.
